The average number of hours of sleep per night was 9.46 hours for a sample of 104 five to seven year-old children. the number 9.46 is a because it is a number that can be computed from the sample of 104 children.

answer: the answer is 23

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

answer: your correct answer is b. d.
